does anybody know the empirical formula of eigenfrequencies of circular membrane?

I need to calculate eigenfrequency analyticaly and compare it with the results the Comsol gives.

Please be kind and write me the formula if you know. The diameter of membrane is 1mm and thickness is 1micron.

Sincerely

Hi

I believe that is to be found on the web, else try a classical book like:
Formulas for natural frequency and mode shape" by R.D. Blevins, Krieger ISBN 1-57524-184-6

It's certainly by your library, and it should be by all structural FEM enfgineers as part of standard V&V of our FEM models

For you case you must also clearly specify how the membrane (and if its a membrane or a plate) is fixed

Good luck
